If you want to perform advanced PetaLinux project configuration such
as enabling Linux kernel options or modifying flash partitions, use the petalinux-config tool with the appropriate -c COMPONENT option.
Important: Only
Xilinx®
drivers or optimizations in the
Linux kernel configuration are supported by Xilinx technical support. For more information on Xilinx drivers for Linux, see https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841873/Linux+Drivers.
The examples below demonstrate how to use petalinux-config to review or modify your PetaLinux project
configuration.
- Change into the root directory of your PetaLinux
project.
$ cd <plnx-proj-root> - Launch the top level system configuration menu and configure it
to meet your requirements:
$ petalinux-config - Launch the Linux kernel configuration menu and configure it to
meet your requirements:
$ petalinux-config -c kernel - Launch the root file system configuration menu and configure it
to meet your requirements:
$ petalinux-config -c rootfs - Use
--silentconfigfor the components when you do not have Kconfig/Menuconfig support or to skip the launching of configuration menu$ petalinux-config -c <COMPONENT> --silentconfig
Warning Message for petalinux-config or petalinux-build Commands
The following warning message appears when you run the petalinux-config or petalinux-build for components (Ex: petalinux-build -c u-boot) and this can be ignored.
WARNING: SRC_URI is conditionally overridden in this recipe, thus several devtool-override-* branches have been created, one for each override that makes changes to SRC_URI. It is recommended that you make changes to the devtool branch first, then checkout and rebase each devtool-override-* branch and update any unique patches there (duplicates on those branches will be ignored by devtool finish/update-recipe).Tip: Set U-Boot target
in
petalinux-config menuconfig as required, for
your custom board. Set as required. Possible values for Xilinx
evaluation boards which are default set are as follows:- For Zynq-7000 devices, xilinx_zynq_virt_defconfig
- For Zynq UltraScale+ MPSoC, xilinx_zynqmp_virt_defconfig
- For MicroBlaze processors, microblaze-generic_defconfig
- For Versal devices, xilinx_versal_virt_defconfig
Note: Please make
sure board and user specific dtsi entries are added to project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi.
Using template flow, for zcu102 and zcu106 boards, add the following
line to <plnx-proj-root>/project-spec/meta-user/recipes-bsp/embeddedsw/fsbl-firmware_%.bbappend
for FSBL
initializations.
YAML_COMPILER_FLAGS_append = " -DXPS_BOARD_ZCU102" #for zcu102
YAML_COMPILER_FLAGS_append = " -DXPS_BOARD_ZCU106" # for zcu106
